摘要
通过氧指数仪、箱式电阻炉、热失重分析仪及锥形量热仪考察了硅藻土对氢氧化镁/红磷协同阻燃三元乙丙橡胶性能的影响。结果表明,随着硅藻土用量的增加,氧指数先增大后减小,硅藻土最佳用量为1.5份;硅藻土可以提高体系的热稳定性及残重率,降低热释放速率。
The influence of diatomite on the flame retardancy of ethylene-propylene-diene monomer with magnesium hydroxide and red phosphorus were investigated by oxygen index analyzer,Neytech vulcan furnace,thermogravimetry analyzer and cone calorimeter.The results showed that with the increase of diatomite amount,the limiting oxygen index increased firstly and then decreased,and the suitable amount of diatomite was 1.5 phr.The diatomite could slightly improve the heat stability and the residual mass of the system and decrease the heat release rate.
